A)As an extension to the voltage ratings given in the Absolute Maximum Ratings section of the TAS5111, TAS5112, TAS5121, and TAS5122 data sheets, this application note gives a more explicit description of the maximum limit for peak voltage vs. time on the BST and OUT pins. Additionally, a measurement technique and test setup is described and application design guidelines given on how to avoid exceed

Music is dynamic, so the power consumption is changing dramatically,from almost zero to maximum within a few ms.Designing the power supply so powerful that it can deliver the total amplifier outputpower continuously is too costly and usually unnecessary.Designing the power supply too small gives p
